The numerical results were compared with relevant experimental data for both the simple and labyrinth side weirs. The results showed that the numerical methodology can effectively predict the discharge and flow profile associated with labyrinth side weirs. The deviation (from experimental data) was found not exceeding 4.5%. Furthermore, the contribution from different terms of the governing equation was assessedthrough a comprehensivesensitivity analysis.  The results show that ,in order to simplify the governing equation, the channel slope and the friction slope can be eliminated.
